SSL and TLS
|
|
========================================
|
|
|
|
.. versionadded:: 1.9.4
|
|
|
|
Botan supports both client and server implementations of the SSL/TLS
|
|
protocols, including SSL v3, TLS v1.0, and TLS v1.1. The insecure and
|
|
obsolete SSL v2 is not supported.
|
|
|
|
The implementation uses ``std::tr1::function``, so it may not have
|
|
been compiled into the version you are using; you can test for the
|
|
feature macro ``BOTAN_HAS_SSL_TLS`` to check.
|
|
|
|
TLS Clients
|
|
----------------------------------------
|
|
|
|
.. cpp:class:: TLS_Client
|
|
|
|
.. cpp:function:: TLS_Client( \
|
|
std::tr1::function<size_t, byte*, size_t> input_fn, \
|
|
std::tr1::function<void, const byte*, size_t> output_fn, \
|
|
const TLS_Policy& policy, RandomNumberGenerator& rng)
|
|
|
|
Creates a TLS client. It will call *input_fn* to read bytes from
|
|
the network and call *output_fn* when bytes need to be written to
|
|
the network.
|
|
|
|
.. cpp:function:: size_t read(byte* buf, size_t buf_len)
|
|
|
|
Reads up to *buf_len* bytes from the open connection into *buf*,
|
|
returning the number of bytes actually written.
|
|
|
|
.. cpp:function:: void write(const byte* buf, size_t buf_len)
|
|
|
|
Writes *buf_len* bytes in *buf* to the remote side
|
|
|
|
.. cpp:function:: void close()
|
|
|
|
Closes the connection
|
|
|
|
.. cpp:function:: std::vector<X509_Certificate> peer_cert_chain()
|
|
|
|
Returns the certificate chain of the server
|
|
